RIVETING--MA CHINE.

Specification of Letters Patent No. 14,137, dated January 22, 1856.

To all whom t may concern.

Be it known that I, EMMoNs MANLEY, of Marion, in the county of IVayne and State of New York, have invented a new and Imroved Machine for Punching and Riveting tovepipe and other Tubing and Things Manufactured from Sheet Metal; and I do hereby declare that the following is a full and exact description thereof, the accompanying drawing being a part of this specification.

Figure 1 is a side view of the machine with sections of the posts a a a a. and the girder Z) broken away for the purpose of showing more distinctly the other portions.

A of Fig. 1 is a lever which by means of the hand rod B of the same figure moves all the parts with the exception of the hammer D. E is a bar of iron on which the anvil d rests and to which some of the other parts are attached.

At e Figs. 1 and 2 is shown the punch which at it's lower end is connected with a spring f Figs. 1 and 2. By thrusting back the hand rod B sov far that the ward g, meets the stop 7L., the spring is compressed by means of a slide Fig. 1 moving on ways, one of which is shown at 7c Fig. l, the slide being operated by the rod F attached to the lever A. The compression of this spring thrusts the punch e upward, and in consequence of its semi-cuneated shape as shown in Figs. 1 and 2 moves the anvil back so as that the end of it comes iiush with the end of the bar on which it rests and allows of the protrusion of the punch through the orifce in the anvil shown at Z Fig. 3 and by the dotted lines at m Fig. 2 so far above its face as to pierce the tops of the sheets to be riveted. The punch being thus protruded is in position to have the sheets laid upon it and to receive a blow from the hammer for the purpose of piercing a hole for the rivet. The hand rod being pulled forward v the punch is drawn below the face of the anvil, and the anvil by means of the spiral spring n Fig. 2 is moved forward so as to furnish a foundation for the rivet, directly over where the orifice for punching was, and directly under the riveting sink in the hammer.

At K Fig. 1 is shown a groove or trough made of t-in or sheet iron in which an apron runs passing over rollers at .0 0 Fig. 1 for the purpose of carrying the rivets which are placed thereon at p Fig. 1 heads downward.

By Fig. 3 is shown the contrivance for carrying forward and placing the rivets on the anvil under the hole punched in the sheets. q Q are mandibles connected toget-her midway each other by a joint in the lateral piece, the ends of which are seen at r Figs. 1 and 8. This lateral jointed piece passes through a slot in the bar on which the anvil rests as seen at s Fig. 1. The hinder ends of the mandibles t, t, Fig. 3 move in sets of grooves made in pieces att-ached to the side of the anvil bar as shown at u Fig. 6 and are held into them by a spiral spring passing through the slot in the anvil bar back of the joint connecting them as seen at o, o, Fig. 3. To the lateral piece connecting the mandibles are lixed friction rollers which traverse a groove made in the anvil bar just above the slot in it parallel with its upper surface as seen at fw Figs. 1 and 3 causing the lateral connecting piece to move always in a plane parallel with the surface of the anvil bar. The grooves traversed by the hinder end of the mandibles are slightly inclined toward each other at the back end and are farther apart at the forward end as seen in Fig. 1. The upper groove m Fig. 1 which the hinder end of the mandibles traverse when moving backward is deeper at the forward end than at the back end for the purpose of allowing the hinder extremities of the mandibles when they lease the lower groove to drop nearer together and thus causing the forward ends to open and lease the rivet standing on the anvil when brought under the hole punched for it. The upper groove being shallower at the back end than the lower one at that point, when the mandibles are drawn back by means of the rods y, y, connecting them with the lever B. The hinder ends of them drop into the lower groove and diverge from each other, bringing the forward extremities nearer each other until arriving at the farthest point back, the forward extremities grasp a rivet and the hinder ones change into the lower groove and the hand rod being thrust back they traverse it to the forward end, and drop upward into the upper groove causing the forward extremities to open and lease the rivet on the anvil and themselves to fall close to the anvil and thus avoid the blow of the hammer.

On one of the rollers over which the apron carrying the rivets passes at 3 Fig. 1 is a ratchet against the under side of which the prong, &c., act and moves forward the apron bearing the rivets every time the hand rod is thrust back.

The hammer is shown at D, Fig. 1. a, the arm of it, is inserted at onexend in an axle lying horizontally crosswise of the machine and boxed in the frame posts a cross section of which is seen at b Fig. 1. The hammer is brought down and the blow struck by it by means of the treadle H Fig. 1 the rod e and the lever b attached to the axle b and is raised to a pependicular position preparatory to a blow by means of a spring 7L coiled around the aXle b and fastened at its upper end to the frame post at 70. Instead of the lever ZJ a wheel may be used with a cord or chain fastened to its periphery at one end and to the treadle at the other, and instead of the form ot spring to raise the hammer described, any other convenient one may be used.

At D Fig. 1 is shown the hammer head which for the purpose of adjustment either Jfor punching the vsheets or heading down the rivets turns on an aXle passing through the stationary shank m. rPhe face and a cross section of the hammer head are shown at- Fig. 4. In the hammer head shown at fn., n, Fig. 4 are two contersinks of depth sutlicient to receive the part ot the punch protruding above the face of the anvil and which at their ends open on the side of the hammer head as shown at j) Fig. 1 for the purpose of discharging the chips cut by the punch. There are also in the face of the hammer head two slight depressions or countersinks shown at 0, 0,'Fig. 4 for the purpose of forming and giving shape to the head of the rivet.

Above the hammer head and on the journal on which the hammer turns are spiral grooves shown at p Fig. 1 into which the dent shown at r Figs. 1 and 5 enters when the hammer is raised preparatory to a stroke. This dent has a joint at s Fig. 5 allowing it to move from its seat in the direction of the spring t and permitting its release from the grooves at the time of the downward movement of the hammer. The spring t drives back the movable limb of the dent 1" to its seat and when in its seat it is immovable in the opposite direction so that when the hammer flies back the spirals being curved in a direction opposed to that in which the dent may move, the dent remains stationary and the hammer head is turned such a part of a revolution as brings the countersink in the face of the hammer for punching, directly over the punch, or the countersink for heading directly over the rivet. Just below the grooves is a ratchet on which a click u Fig. 1 acts, for the purpose of preventing the hammer from being turned backward by the dent r at the beginning of the stroke.

L Fig. 1 is a holder for the clasp which keeps in place on the anvil the sheet or tube to be riveted. It is adjustable in respect to height by the slide on the post at o Fig. 1 and by the pin holes at w Fig. 1.

Fig. 6 is a view of the clasp for holding the sheets or tubes to be riveted. are

nibs which enter the holder L. y, y, are

straps of hoop or band iron which reach across and lap over the opposite side of the clasp and keep in place the sheets or tubes to be riveted.

What I claim as my invention and desire to secure by Letters Patent is- The arrangement of the punch e, lever A and mandibles g in relation to the anvil cl, and self-adjusting hammer head D in the manner and for the purposes set forth.

EMMoNs MANLEY.
